In a fruit juice facility, pear juice is heated from 20 C (feeding temperature) to 90 C with a heat exchanger to be pasteurized. The heat requirement of the system is met by converting the saturated steam at 127.0 ºC into a saturated liquid at the same temperature. Since the pear juice has 20 Brix, calculate the amount of steam required for this process (kg steam / kg pear juice). Note: There is a heat loss of 10% of the energy required for heating the fruit juice in the system.
